Subject: tools/bpftool: Emit name <anon> for anonymous BTFs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=71ccb50074f31a50a1da4c1d8306d54da0907b00;p=linux.git

tools/bpftool: Emit name <anon> for anonymous BTFs

For consistency of output, emit "name <anon>" for BTFs without the name. This
keeps output more consistent and obvious.
